What is Area Unit Conversion?
Area unit conversion is the process of expressing the same two-dimensional measurement in a different unit. All area units are derived from length units squared — for example, 1 m² equals 1 meter × 1 meter. The area converter uses a single base unit (square meter, m²) as the pivot: every input is first converted to m², then scaled to the target unit using a precise conversion factor. This two-step approach guarantees accuracy across all 10 supported units, from tiny mm² to vast km² and mi².
How Our Area Converter Works
- 1Select your units: Choose the source unit (From) and the target unit (To) from the dropdowns. Use the swap button to instantly reverse the direction.
- 2Enter your value: Type any positive number into the input field. The area converter accepts integers and decimals of any size.
- 3Get your result: Click Convert to see the converted value instantly. Expand the all-units table to view the equivalent in every supported area unit at once.
Metric Area Units
mm², cm², m², km², and ha (hectare) follow the SI system. Each step is a factor of 100 (for squared units) or 10,000 (for hectares). Used globally in science, engineering, and most countries.
Imperial & US Area Units
in², ft², yd², and mi² are used primarily in the United States and UK. 1 ft² = 144 in², 1 yd² = 9 ft², and 1 mi² = 3,097,600 yd². Common in real estate, construction, and everyday US measurements.
Agricultural Units
Acres (ac) and hectares (ha) are the standard units for land area. 1 acre ≈ 4,047 m² and 1 hectare = 10,000 m². 1 acre ≈ 0.405 hectares. Used worldwide for farm land, property, and national park measurements.

An area converter is a tool that converts a measurement of two-dimensional space from one unit to another — for example, from square feet to square meters, or from acres to hectares. Our area converter supports 10 units across metric, imperial, and agricultural systems and runs entirely in your browser with no signup required.
1 square meter (m²) equals approximately 10.7639 square feet (ft²). Conversely, 1 square foot equals approximately 0.0929 square meters. Use the area converter above to convert any value between m² and ft² instantly.
1 acre equals exactly 4,046.8564 square meters. To convert acres to m², multiply the number of acres by 4,046.8564. For example, 5 acres = 5 × 4,046.8564 = 20,234.28 m². The area converter handles this calculation automatically for any value you enter.
1 hectare (ha) = 10,000 m², while 1 acre ≈ 4,046.86 m². This means 1 hectare ≈ 2.471 acres, or equivalently 1 acre ≈ 0.4047 hectares. Hectares are the metric standard used in most countries, while acres are common in the US and UK for land measurement.
1 square kilometer (km²) equals approximately 0.3861 square miles (mi²). Conversely, 1 square mile ≈ 2.59 km². These units are used for large geographic areas like countries, national parks, and cities. Enter your km² value in the area converter and select mi² as the target unit.
Yes, completely. All area conversions are performed locally in your web browser using client-side JavaScript. No values, inputs, or results are ever sent to any server. Your data stays entirely on your device.
Yes. The area converter supports cross-system conversions between all metric units (mm², cm², m², km², ha) and all imperial/US units (in², ft², yd², mi², ac). Simply select any combination of source and target units — the converter handles the math automatically.
The smallest unit supported is the square millimeter (mm²). 1 mm² = 0.000001 m² = 1 × 10⁻⁶ m². This unit is commonly used in engineering, electronics, and precision manufacturing where very small cross-sectional areas need to be measured.
Yes, the area converter is 100% free with no account registration, no payment, and no usage limits. You can convert as many area values as you need, any time, on any device.
